SPECIFICATION forming part Of Letters Patent No. 520,861, dated June 5,1894. Application filed December 15, 1893. Serial No. 493,723. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, HENRY OSHEA, a citizen of the United States,residing at J ohnstown, county of Oambria, and State of Pennsylvania,have invented a new and useful Improvementin Railway-Frogs, of which thefollowing is a true and exact description, due reference being had tothe accompanying drawings. U

My invention relates to an improvement in railway frogs and method ofconstructing the same and has for its object to provide a frog havingbut few parts and one in which the girder'feature'of the web of the railis largely preserved. As ordinarily constructed frogs are formed of twoor more rails cut and fitted together. lVhen two rails are used the tophalf of one and the lower half of the other must be cut away or they arehalved into each other as it is called. This of course greatly weakensboth rails and renders them more liable to fracture at that point. Whenconstructed of three or more pieces the multiplicity of pieces rendersthem liable to derangement and loosening of thevarious fastenings. By mymethod I am enabled to produce a frog composed of two integral membersthe girder webs of which are continuous fromend to end,'the two webspassing beneath the point and-supporting it so that that part of thefrog which supports the traffic of both lines of rails is the stiifestand strongest of the structure.

Referring to the drawings in which the same letters refer to the sameparts: Figure 1 represents a topview of a frog embodying my invention,said frog being composed of side bearing girder rails. Fig. 2. is a sideView and Fig. 3 an end view of same. Figs. 4. and 5 are elements of thestructure as hereinafter explained. Figs. 6, 7 and 8 represent a frogconstructed of T rail in accordance with my invention and Figs. 9, 10and 11 show one composed of girder guardrails.

In general my frog is composed of tworails bent to the proper angle andhaving enough of one side of each cut away to allow them to be securedtogether by bolts or rivets through both the webs. Fig. 6 illustratesthis in the case of a T rail frog, A and B being the two rails whichafter being bent to the proper an gle for the frog are planed orotherwise cut away so that they shall fit together on the line XX. Thiscutting allows the two webs w-w to come together beneath the point P.The two members are then secured together by the rivets or bolts shownpassing through both webs. The grooves G. permit the passage of theflange of the car wheel. This construction serves when the section ofthe rail is symmetrical on both sides of the web,

as a T rail or a center bearing girder rail whether the same be providedwith guards or not, but when a side bearingrail such as is commonly laidin street railways, in which term is included a side bearing guard rail,is used something more must be done as it will be seen that on one endof either rail the wheel flange travels on the right hand side of thehead and on the other end of the same rail the flange is on the lefthand side of the head.

Toprovide a rail such as is needed 1 proceed as follows: In Fig. 4 A, Arepresent two pieces of side bearing girder rail adapted to form therail A Fig. 1. It will be seen that in'A', the head is on one side whilein A the head is on the other side. In A the head H is allowed toproject as shown and it is severed from the remainder of the rail onalevel with the top of the tram T back to apoint as O. The ends of thetwo rails are then bent at the proper angle and the webs w and lowerflanges welded together, in fact as much of the two sections as aresymmetrical on both sides of the web are united. This welding of the twotogether unites them into one integral rail one end having the head onone side and the other end having the head on the other side as desired.The head 11 is now riveted or otherwise secured to the trainT andfurther stiffens the j unction.- If desired the head H. may be welded tothe tram T. This integral rail now has all the surplus metal cut away tothe line XX Fig. .5 and is then ready to be secured to the correspondingrail B. of Fig. 1. The portion H. of the head serves as guard or wingrails and supports the car wheel as it passes the point P. In a case asshown in Fig. 9 when the railhas an elevated guard instead of a flattram it would be necessary to adapt the guard to receive the head. Inthe drawings it is shown cut away but a slight modification of the railmight require the guard to be bent down instead, or otherwise treated.It will of course be seen that various shapes of rails might requireslight modifications in the cutting and fitting together but suchchanges would readily suggest themselves to one skilled in the art.

By the wing I mean all that portion of rail from where the main trackrail joins the frog portion as A Fig, 4, and by point railImean all thatrail lying from the point to where the main track rail joins as A Fig.i.

The term side bearing rail where used in the specification and claims isintended to cover that class of girder rails in which the head projectsto one side in part or in whole of the web and is not symmetricalthereto, such as the side bearing groove rail, side hearing tram railand side bearing guard rail.

The word tram is used to designate that part of the rail projecting fromthe web at the side opposite to the head and which in a guard or groovedrail is sometimes designated the floor or groove.

Having thus described my invention, what I claim, and desire to protectby Letters Patcut, is

1. A railway frog composed of two rails bent and fitted together so thatboth webs are continuous beneath the point, substantially as described.

2. A railway frog composed of two side bearing girder rails bent andfitted together so that both webs are continuous beneath the point.

3. A railway frog composed of two rails bent and fitted together, eachrail comprising a wing portion and a point portion the webs c 45 5. Arailway frog composed of two side bearing girder rails, each railforming the wing and point portions on the same side of the frog, theweb of each rail being formed continuous from wing portion to pointportion.

6. In a railway frog a rail bent to the desired angle of the frog, oneend of the rail forming a point portion and the other end forming a wingportion of the frog.

7. In a railway frog, a rail bent to the desired angle of the frog, oneend of the rail forming a point portion and the other end forming a wingportion of the frog, the web of the rail being formed continuous betweenthe wing and the point portions.

8. In a railway frog composed of side bearing girder rails, a rail bentto the desired angle of the frog, the head of the rail being formed onopposite sides of the web on the two ends of the rail.

9. In a railway frog composed of side bearing girder rails, a rail bentto the desired angle of the frog, the head of the rail beingdiscontinuous, the two portions being on opposite sides of the web, andthe head of one end overlapping and being secured to the tram ofthe'other end.

In testimony whereof I have affixed my signature in presence of twowitnesses.

HENRY OSIIEA.
